There are three key ways in which computers have improved communications.
The first way in which computers have improved communications is by lowering the cost of communicating. Indeed, thanks to advances in computer technology, we can now communicate with people who are very far away through free email, or through free IP-based telephone calls.
The second way in which computers have improved communications is by enhancing the speed of communications. Computers have also made it possible for people to communicate conveniently.
And the third way in which computers have improved communications is by doing away with geographical limitations, which used to make communication difficult. It is worth noting, for instance, that thanks to email systems such as Gmail – which can either be accessed through the links provided in this blog or by going through the URL mail.google.com – people of different nations can communicate in an unhindered fashion. Things were not always that way. Just a few decades ago, communicating with people in other nations would have necessitated the use of either telephone, fax or international snail mail, all of which were carefully monitored by agents of the stage. Needless to say, all such international communications would also tend to be extremely costly.
